Longtown is a village in Union Township in Perry County, Missouri, United States.

Some of the earliest Europeans to put down roots in the area were English and Scotch-Irish Presbyterian settlers from Rowan, Iredell, Cabarrus, and Mecklenburg counties in North Carolina who settled to the south in Brazeau in 1817.

Soon after, in 1821, they were followed by English and Scotch-Irish Methodists also hailing from North Carolina, settling in the present area of Longtown.

[5] These settlers were part of a large exodus from the Piedmont region of North Carolina following the War of 1812.

[6] In 1826 these settlers built their first log meeting house which was replaced with York Chapel Methodist church in 1836.

[11] Up until 1881 the Protestant German population had been members of the Frieden (Peace) Lutheran Congregation in nearby Friedenberg.

However, due to the dirt roads becoming impassable in wet seasons or freezing temperatures in winter, the need for a local church had grown.

By 1883, the members of Cross Lutheran church had been asked to leave the schoolhouse as the building belonged to "Longtowners".

Wetzel moved to a different location, more north-east of Longtown and organized and built the Cross Lutheran Church, Ohio Synod.

[12] In the early part of the 20th century Longtown had a population of 158, with two churches, a public school, three general stores, a bank, a tavern and a flouring mill, and had largely remained a farming community.

[13][14] On April 20, 1936, the Hacker & Funke General Store and Barbershop had suffered severe fire damage.

[15] According to the United States Census Bureau, the village has a total area of 0.13 square miles (0.34 km2), all land.
